The first pcDuino board powered by AllWinner A10 has been available for about a year, later last year pcDuino V2 was released with a built-in Wi-Fi modules and mechanically and software compatible Arduino headers, and now pcDuino3 has been announced in a form factor similar to pcDuino V2 board but replacing AllWinner A10 Cortex A8 SoC with AllWinner A20 dual core Cortex A7, and improving overall specs such as faster Ethernet, the addition of a SATA port, and LiPo support.

The board also called “pcDuino Dual core” will come with support for Ubuntu 12.04 and Android 4.2, but you’ll be able to run any Linux distributions, with some caveats related to GPU and VPU support in Linux, although this may be fixed overtime thanks to work from linux-sunxi community.

The company also provides an API to control the signal available via the Arduino heders (UART, ADC, PWM, GPIO, I2C, SPI), and you should be able to use Arduino shields that are compatible with Arduino UNO.

The board is available now, and can be purchase starting from $77 via sites Linksprite or Sainsmart. Price may or may not include shipping depending on the destination. Price looks OK, as the specs place the board between Cubieboard2 ($59) and Cubietruck ($89) both featuring AllWinner A20 with a different set of hardware features. You can get more information on pcDuino.com, and more pictures and a pcDuino V2 vs pcDuino3 comparison tablet are also available on Sainsmart blog.
